Drive Plate Misalignment

WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

Common causes of misalignment are:

  1. Heat warping
  2. Mounting drive plate on a dirty crankshaft flange
  3. Incorrect bolt tightening
  4. Improper seating on the crankshaft shoulder
  5. Loose crankshaft bolts

Clean the crankshaft flange before mounting the drive plate. Dirt and grease on the flange surface may misalignment the flywheel, causing excessive runout. Use new bolts when mounting drive plate to crankshaft. Tighten drive plate bolts to specified torque only. Over-tightening can distort the drive plate hub causing excessive runout.
